A description of current and emerging network technologies.
Content must include:-
• Network technologies: operating systems; protocols; layout; devices
• Networking operating systems: examples eg Windows, Linux
• Networking protocols: eg SNMPv3, ICMP
• Layout: eg cabling, topologies, wireless
• Network devices: servers; workstations; interconnection devices; network cards; vendor specific hardware
Task 2
Describe the purpose of networking tools
• Networking tools: purpose eg fault management, performance management; specific examples of tools eg HP Open view, Cisco Works, Wireshark; using system software eg to find network assets
Task 3
Identify emerging technologies and how they have, or may affect networks
• Impact of emerging technologies: enhanced capabilities eg faster, greater storage capacity, improved control; new work methods eg mobile working, home working, web centric applications; ease of use
• Emerging technologies: examples eg server virtualization, video on demand
Task 4
Explain the functions of network management
• Network technologies: operating systems; protocols; layout; devices
• Networking operating systems: examples eg Windows, Linux
• Networking protocols: eg SNMPv3, ICMP
• Layout: eg cabling, topologies, wireless
Task 5
Explain the goals of fault management and the consequences of failure
Task 6
Justify why routine network performance management should be carried out, including reference to quality and efficiency. +400 words, include references .
Fault management is the process of detecting, diagnosing and resolving faults or errors in a network system. Fault management typically consists of the three steps; detection, diagnosis, and resolution. The goal of fault management is to reduce network downtime and maximize service quality for users by providing an efficient way to detect, diagnose, and resolve faults quickly and accurately.
Performance management is critical to any successful IT operations-based organization as it enables an understanding of how well services are being delivered from both a customer perspective as well as from a technical perspective. By having an accurate performance measurement system in place, organizations can better manage their resources including personnel and equipment with increased efficiency while improving customer satisfaction levels through higher service quality delivery. Performance management also enables cost savings through identifying areas where processes can be improved or automated leading to reduced resource utilization resulting in lower operational costs.
Routine network performance management should be carried out on regular basis–at least once per quarter–in order to ensure optimal functioning of networks across all sectors within an organization. Regular monitoring allows administrators to keep track of changes that may occur over time because of environmental factors such as fluctuating temperature, humidity etc., which can cause strain on hardware components due to thermal stress or corrosion caused by dust build up among other things . Network performance monitoring can help identify potential issues before they become real problems so that proper preventive measures can be taken accordingly before disruption starts occurring internally/externally affecting user experience & ultimately leading revenue loss or reputational damage due to poor Quality Of Service(QoS). Routine performance monitoring also helps improve efficiency levels by aligning IT objectives with business goals since it provides valuable insight into current infrastructure & technology trends that impact user productivity & agility giving vital clues towards optimization prospects (Zhang et al.,2015).
In conclusion , routine network performance monitoring has far reaching benefits ranging from improved reliability & QoS , better alignment between IT objectives & business strategies along with making sure resources are used optimally without wasteful expenditure leading towards greater overall efficiency in long term-. As emphasized by Rajendran et al.(2020) “Effective useof such techniques leads not only toprecise decisions butalso saves money” thus providing ample justification for undertaking regular routine network performance analysis& audit exercises periodically .
